The new ALP acoustic guiding profile is a thermal guiding profile that improves the acoustic effectiveness (+20 %) of the metal ceiling perforation and the heating and cooling performance (+20 %) compared to conventional thermal guiding profiles thanks to its raised louvres. The ALP covers much less acoustically effective surface area than conventional heat conducting panels. The incident sound energy can be absorbed, but the thermal energy is still transferred to the water-bearing pipes. Bending up the fins increases the heat exchanger surface in the cassette cavity (e.g. finned heat exchanger). Furthermore, the bent-up fins optimise the convective transfer. No material is wasted due to the partial bending up of the fins.
